Agatha Christie's Surprise Ending vs. Wikipedia

Since 1952, Agatha Christie's murder-mystery play 'Mousetrap' has
been playing in London theaters, clocking an estimated 24,000
performances. And each time, at the end of the play, theatergoers are
warned not reveal the murderer and thus spoil the ending for prospective
audiences. Agatha Christie's family, and fans, would now like to extend
that quaint courtesy to potential viewers who may stumble upon the
play's Wikipedia page.

My
grandmother always got upset if the plots of her books or plays were
revealed in reviews – and I don't think this is any different,"
[Prichard] said. "I think it is a pity if a publication, if I can call
it that, potentially spoils the enjoyment for those people who go to see
the play. It's not a question of money or anything like that. It's just
a pity."

He, and apparently hordes of fans, are petitioning
Wikipedia to take down the spoiler from the page--or at least add a
"Spoiler Alert" caveat. Wikipedia, according to a spokesperson interviewed by
The Independent, isn't budging:

It's exceedingly easy to avoid knowing the identity of the murderer: just don't read it.
